Problem

Find the area of the triangle whose height is \$36cm\$ and the base is \$1/8\$th the length of the height.

Step

Given height is

\$36cm\$

Step

Now calculate the Base length

\$(1/8) \times h\$
⇒ \$36/8 (cm)\$
⇒ \$4.5cm\$

Formula:

Area of Triangle

\$(1/2) \times b \times h\$

Step

Substituting values

\$(4.5 \times 36)/2 (cm)^2\$

Step

After simplification

\$162/2 = 81 (cm)^2\$

Step

Therefore,Area of the triangle is

\$81 (cm)^2\$
